Marzip

Introduction

Marzip is a container format for storing collision avoidance related files. This is a normal zip file that uses a custom extension (.marzip) to indicate the data stored is from the maritime domain.

The following files make-up a marzip file:

File	Description
manifest.json	manifest file containing the marzip version.
traffic_situation.json	the traffic situation, described here.
situation_output.json	the situation output, described here.
ship_static.arrow	part of the simulation output, described here.
time_series.arrow	part of the simulation output, described here.

Compression

To compress the marzip file, DEFLATE compression, or no compression (STORE) can be used. To maximize compatibility, it is discouraged to use other compression types.
